I think the issue, especially for these reviewers who've been used to driving much more powerful (and expensive) cars, is the Emira looks like it should perform like those types of cars, but it doesn't. It isn't a thundering exciting car to drive. It isn't raw and wild; it's a refinement car. Henry picked up on that with the steering; it rewards finesse, not muscle. I also think it fitting that he talks about Jim Clark, who I have no doubt would have been really impressed with the Emira. It's his kind of car, and rewards his style of driving.
How thrilled you are with it is going to depend a lot on what you're used to. Remember that its target design price point was £59,995. The FE is that car with all the options included, but it's still a £59,995 at heart. It looks like cars that are 3 times as expensive, but that's a bonus; it doesn't have the drivetrain of cars at that price. Set your expectations accordingly.
The issue with the steering turn-in is odd. Chris Harris didn't mention anything of the sort, but he was driving a tour chassis with Goodyears. There seems to be something going on with the Goodyears on the sport chassis. Gavan must have had Goodyear tune them just for the tour chassis, and Michelin for the sport, and that's where they perform best. Toe-in and camber can be adjusted once you get your car, but I suspect this car is going to be one of those that really makes you feel the difference in tires.
For a car designed for a base price of £59,995, I don't expect perfection in every way. As long as the basics are there, it will be like any other car; you can mod it afterwards to get it where you want it to be. One thing you won't need to mod are the looks; as Henry pointed out, it looks fantastic no matter where it is.
